Sodium bicarbonate is made commercially by one of two methods. In the first method, carbon dioxide gas is passed through an aqueous solution of sodium carbonate (Na2CO3): Since the bicarbonate is less soluble than the carbonate, it precipitates out of solution and can be removed by filtration. Sodium bicarbonate is also obtained as a byproduct of t...
Sodium bicarbonate is a very effective cleaning agent for certain materials. In the 1980s, restorers used an aqueous solution of the compound to clean the Statue of Liberty.
An estimated 560,000 metric tons (615,000 short tons) of sodium bicarbonate were consumed in the United States in 2003. About one-third of that amount was used by the food products industry, primarily in the manufacture of baking soda (pure sodium bicarbonate) and baking powder (a mixture of sodium bicarbonate and at least one other compound). Baki...

Sodium bicarbonate is a white crystalline solid, typically appearing as a fine powder. It is odorless, has a salty, alkaline taste, and is soluble in water. It releases carbon dioxide gas when heated or when reacting with acids, a property exploited in baking and fire extinguishers.
Description. Sodium bicarbonate appears as odorless white crystalline powder or lumps. Slightly alkaline (bitter) taste. pH (of freshly prepared 0.1 molar aqueous solution): 8.3 at 77 °F. pH (of saturated solution): 8-9. Non-toxic. CAMEO Chemicals. Sodium hydrogencarbonate is an organic sodium salt and a one- carbon compound.
Sodium bicarbonate, also known as baking soda, is a widely used chemical compound with the formula NaHCO 3. This white solid crystalline substance has diverse applications, spanning across various industries such as food, health, cleaning, and more. Chemical and Physical Properties.
